The TAN tells you how acidic the oil has become. Choose TAN for just that one test, or Oil + TAN to add a TAN onto a standard oil analysis.
TAN
Price range: $25.00 through $50.00
Description
This test is based on ASTM Method D664 and gives you an idea about how acidic an oil is.
As an oil sees use (especially engine oil), it can become more acidic and that acidity can lead to break-down of the oil.
This test is useful if you are interested in extending your oil use, since a significant increase in the acidity of an oil will often be the precursor to the viscosity reading out of line and oil sludge starting to form.
The test itself is fairly simple. A weighted portion of oil is added into a beaker. Titration solvent is added that allow the machine to measure the pH of the mixture as it is stirred. The machine then starts to add a basic solution to the mixture and when the whole solution reaches a pH of 11, the test is complete.
Minimum oil required: 10 ml
